The type K-A is equipped: a) with embedded double boars, which are on the same level on both sides of the column and are designed to adjust the crossbars with a cross section of 60×16 cm> b) embedded strips on both sides of the column, to which tables for liners are welded.
The type of K-B is equipped: a) with embedded double boars, which are at different levels on both sides of the column and are designed to adjust the crossbars with a cross-section of 60×16 and 40×16 cm; b) embedded strips on both sides of the column, to which tables for liners are welded.
The type of K-B is characterized by: a) a mortgage double-barrier on one side of the column, designed to adjoin the crossbar with a cross section of 60×16 cm; b) embedded strips from the other three sides of the column, to which supporting tables for liners and crossbars of small spans are 3.6 m.
Stags of 3.30 m long per height of one floor are used six sizes and three types: K-A, K-B and K-V, which differ from two-story columns only with length.
The design of rectilinear columns that were used in construction (in 1954-1955.) frame-panel houses in the area of sand streets in Moscow.
The bearing capacity of the columns at the central load was accepted from 109 to 241 tons, which ensures their use in nine-one-earnest residential buildings. The section of the columns is selected by normal strength, taking into account the eccentricity, determined from the moment of pinching of the crossbar in the column. To determine the influence of eccentricity on the bearing capacity of the column, you can use a special table of the column variety.
